capacitor is​

Answer 1

$\tt {i = \frac{V} {Xc}}$

$\tt{V = iXc}$

$\tt{= \frac{i} {wC}}$

$\tt{ \frac{2 \times {10}^{ - 3}}{2\pi \times 1000 \times 2 \times {10}^{ - 6}}}$

$\tt{ = 0.16 V}$

Answer 2

$\huge\tt \red {i = \frac{V} {Xc}}$

$\huge \tt \green{V = iXc}$

$</p><p> \huge\tt \pink{= \frac{i} {wC}} </p><p></p><p>$

$\huge\tt \orange{ \frac{2 \times {10}^{ - 3}}{2\pi \times 1000 \times 2 \times {10}^{ - 6}}}$

$\huge\tt \purple{ = 0.16 V}$
